IMPROVEMENT IN CARTRIDGE-EXTRACTORS FOR BREECH-LOADING FIRE-ARMS.

Specification forming part of Letters Patent No. 172,448, dated Januaryv18, 1876; application l'ed June 12, 1874.

To all whom it may concern:

Be it vknown that I, JOHN W. KEENE, of Newark, in the county of Essexand State of New Jersey, have certain Improvements in CartridgeExtractors for Breech Loading Fire-Arms, of which the following is aspecitication:

My invent-ion relates to certain improvements designed more particularlyfor application to breech-loading fire-arms similar to those for whichLetters Patent were heretofore granted to ine-namely, February 24, 1874,and March 17, lS7-i--although they may be applied to breech-loaders ofany suitable construction.

The invention consists in a rigid lever working in a recess in therecoil-block or front portion of the bolt or breech block, and pivotedor balanced near its center, the front portion of said lever beingformed for engagement with the flanges ofthe cartridge, and the rear endfor engagement with a cam on the bolt and with the cover of thereceiver, so that when the bolt is moved forward to close the breech thefront end otl the lever does not catch over the liange until the bolt isrotated to the right to lock the gun,when the lever is locked in itsengagement with the flange, and so remains until the backward mot-i011ot' the bolt, when the lever is released from the ange by the contactot' its rear end with the cover or other iixed point.

In the accompanying drawing, Figure 1 is a central longitudinal sectionot' a bolt or magazine gun embodying my improvements with the. breechclosed. Fig. 2 is a similar view with the breech open. Fig. 3 is atransverse section in the line .fr a' of Fig. l. Fig. 4 is a perspectiveview of the extractor. Fig. 5 is a sectional view ot a moditication.Fig. 6 is a front view of the same. Fig. 7 is a perspective view of amodification of the extractor.

The several figures represent my improvements as applied to a single-loadin g or magazine gun, although said improvements may be appliedto guns of any suitable construction.

The receiver A and bolt B are similar to those shown in my patentsaforesaid.

In the recoil-block C and the under part of the strap D is a recess orcavity, in which works a rigid lever, E, which is pivoted 0r balancednear' its center by the engagement ot' a projection, e, on its underside, with a depression in the cavity in the recoil-block. The front endof the lever E is formed with a catch, f, of suitable form to enable itto ride over the rim ot' the cartridge. The rear end ot' the lever E isformed with a projection, g,

on the upper side, and another projection, L,

on the under side, the former working 1n an opening in the strap D, soas to extend slightly above the top of said strap, and the latterengaging with a cam, b, on the front end of the bolt B, formed bycutting away a portion of the metal on said front end.

When the bolt is moved forward to close the breech the catch f does notengage with the ange of the cartridge until the handle is turned to theright to lock the bolt or gun, when the cam b bears against theprojection h, raisin gthe rear end ofthe lever and depressing. the irontend, and thus locks the lever in its engagement with the rim of thecartridge. When the handle is turned up and the bolt moved back thefriction of the lever in its recess or cavity is suiicient to retain itin position until, in the backward motion ofthe bolt, the projection gcomes in contact with and passes under the cover ot' the receiver orsome other iixed point, when the rear end ot' the lever is depressed,and the catch or front end raised and released from the rim, and leftfree to enga-ge with the rim of another cartridge. The shell is ejectedby means of the ejector pin l, or other suitable device.

In Figs. 5, 6, and 7 I have shown a modification ofthe form of theextractor, in which the lever E is hung or pivoted at its rear end, sothat the hook f slips over the rim ofthe cartridge and drops of its ownweight, and is locked by passing under the front portion of the cover ofthe receiver.

These modifications may be applied to guns the construction of whichwill not admit ot' the application of the lever in its elongated form,although they may be applied to boltguns without changing the principleof the invention.

What I claim as new, and desire to secure by Letters Patent, is-

l. A cartridge-extractor for breech-loading 2 IQALIS fire-arms,consisting of a rigid lever pivoted or balanced at a point between theends, having its front end formed for engagement with the rim of thecartridge, and its rear end for engagement With the bolt or breech blockto hold it to said rim, and with the cover of the receiver to release itfrom said rim, substantially as shown and described.

2. The combination of the extractor E and the front end of the breechbolt or block for locking the extractor in contact with the rim of thecartridge, as shown and described.

3. The combination of the extractor E and the cover of the receiver, orother fixed point, for unlocking the extractor on the backward motion ofthe bolt, substantially as described.

The foregoing specification of my invention signed by me.
